我需要在本地计算机上运行客户端软件，并通过VPN链接（Team Viewer VPN）进行通信以连接到实时数据库，以便将debugging程序附加到客户端软件，并解决客户端遇到的一些问题。
当客户端networking上的任何一台计算机连接它工作正常。 这是驱动程序debugging信息的输出。

我认为可能出现的一些问题是Team Viewer希望我通过它的特殊IP路由stream量，而不是通过它传输广播。 我试图告诉TCP / IP连接使用服务器的IP和端口，但是这也没有解决问题

有一点我注意到端口没有列在Trying 7.192.141.131即使我明确地告诉它使用那个端口，工作日志中的同一行显示包含Trying 192.168.0.2:2638的端口。
防火墙在客户端和服务器上都是禁用的，所以问题与此无关，我想这是因为端口号没有设置，但我不知道我在做什么错误导致它不被设置。
这是使用Adaptive Server Anywhere 7.0驱动程序。
